Meritline offers the MEElectronics M9P Sound-Isolating Headphones in Black for $17.99. Coupon code "MLCWNDN" cuts them to $11.99. With free shipping, that's the lowest total price we could find by $3, although we saw a silver pair for a buck less in November. This headset features an inline microphone, 9mm drivers, frequency response of 20Hz to 20kHz, 3.5mm gold-plated plug, and more. Coupon expires January 9.
